“I was an only child, and it was lonely,” Barrymore says in the September issue of InStyle, which she covers. “Some people love it and thrive on the independence, but I want my kids to have other kids around. Maybe two kids so they can run around life together, roll their eyes at their parents together like Rusty and Audrey Griswold from ['National Lampoon’s'] 'Vacation.' So however that’s going to come about, it’s gonna happen!”

"I love the person who said, 'Parenting is like wearing your heart on the outside of your body.' It’s the most beautiful, perfect analogy," she tells InStyle. "I have anxieties about how much I’d like to get it right, making sure I provide her with an environment that’s safe, nurturing, and loving. And silly and free, also consistent and grounding. Then I just have the same typical fear every other parent has: Are they going to fall down?"
